UNITE STATES PATENT JOHANN J. PETERS, 0E REINFELD, SASKATCHEWAN, CANADA.

GULTIVATOR.

To all whom it may concern:

Be it known that I, JOHANN J. PETERS, of the village of Reinfeld, in theProvince of Saskatchewan, Canada, have invented certain new and usefulImprovements in Cultivators, of whichthe following is the specification.

The invention relates to improvements in cultivators and the object ofthe invention is to provide a cultivating machine which will efiectivelycultivatethe ground, a particular feature of the invention residing inthe provision of specially constructed cultivator blades suspendedsothat they can be adjusted in respect to the ground and in theprovision of colters associated with the blades and adjusted with theSame.

WVith the above objects in view the invention consists essentially inthe arrangement and construction of parts hereinafter more particularlydescribed and later pointed out in the appended claims, reference beinghad to the accompanying drawing in which:

Figure 1 represents a plan view of the complete machine. Fig. 2represents a longitudinal sectional view through the same, the sectionbeing taken in the plane denoted by the line X-X Fig. 1, with partsbroken away. Fig. 3 represents a rear view of one of the cultivatorblades. Fig. 4 represents an enlarged detailed sectional view throughone of the brackets showing the connection of the lever 34 to theadjusting shaft.

In the drawing like characters of reference indicate corresponding partsin each figure.

1 represents a substantially rectangular frame formed from suitableconnected side members 2 and 3 and front and rear end members 4 and 5.

6 and 7 represent stub shafts permanently fastened to the sides of theframe and pro- Specification of Letters Patent.

bars interposed between the draft bars and the frame.

21 and 22 represent similar front and rear ad ust ng shafts rotatablymounted in front and rear sets of brackets 23 and 24 permanentlyfastened by bolts 25 to the front and rear members of the frame.

26 and 27 are a pair of hangers extending rearwardly from the shaft 21and permanently fastened to the same by pins 28. The rear ends of thehangers carry a front cross shaft 29, 7

30 and 31 are a further pair of hangers extending forwardly from theshaft 22- and permanently fastened to the same by pins These latterhangers carry a rear cross shaft 33.

34 is a front lever permanently fastened to the adjusting shaft 21 bymeans of a'pin 35. The lower end of the lever is sup-plied with arearwardly extending arm 36 having therear end mounted on the shaft 29.

37 is a quadrant carried by the frameand associated with the lever. Thelever is supplied with the usual hand latch 38 and detent; 39, thedetent operating over the quadran 40 is a second lever supplied with aforwardly extending arm 41 having the front end thereof mounted on thecross shaft 33.

42 1s a detent and 43 a hand latch carried by the lever, the detentoperating over a quadrant 44 connected to the rear cross member of theframe.

45 is a central and 46 and 47 are side cultivator beams, which beamshave their front and rear ends swung from the shafts 29 and 33.

A cultivator blade 48 is secured'permanently to each beam and the beamsare bent in a peculiar manner in order to stagger the blades across themachine.

Each blade is formed from a metallic plate having a tapering bodyportion 48 of a V-shaped cross section which terminates in a point andcarries at the sides horizontally disposed V-shaped wings 48 and 48 toadmit the colters. It is pointed out also that there is a colterdirectly in advance 0 each cultivator blade and that the colterE" isarranged to cut at all times deeper than the point of the blade.

51 is a seat mounted on a suitable cross board 52 carried by the frame.

WVhen the machine is used and drawn over the ground by the usual draftanimals hitched to the double tree, the driver or attendant canmanipulate the levers to adjust the cultivator blades to effect shallowor deep cultivation, the levers also controlling the pitch of theblades.

It will be seen that if both levers be swung inwardly approximately alike amount the front and rear ends of the beams Will be dropped evenlywith the result that the depth of out only is efi'ected. On the otherhand if one lever only is adjusted the beams are tilted in respect tothe ground with the result that the angle of the cultivators to theground is changed.

With the machine as described effective cultivating can be done underthe varying conditions met with in the field owing to the manner inwhich the cultivating blades can be adjusted to meet requirements.

lVhat I claim as my invention is In a cultivator the combination with amain frame mounted on suitably supported f Wheels, of front and rearrotatably mounted adjusting shafts passing transversely across theframe, a pair of rearwardly extending hangers having their forward endspermanently secured to the front shaft, a pair of forwardly extendinghangers having their rear ends permanently secured to the rear shaft,front and rear cross shafts carried by the hangers and contained Withinthe frame, front and rear adjusting levers permanently secured to thefront and rear adjusting shafts and provided each, adjacent the saidadjusting shafts, with inwardly extending arms having their innermostends mounted respectively onthe cross shafts, quadrants carried by theframe and associated with the levers, a plurality of substantially L-shaped, longitudinally extending cultivator beams disposed Within theframe and having their front and rear ends swung from the cross shaftsand cultivator blades permanently secured to the lowermost portions ofthe beams.
